<h1>React Performance Optimization Techniques</h1>
<p>Performance optimization is crucial for delivering a smooth user experience. Let&#39;s explore various techniques to optimize React applications.</p>
<h2>Key Optimization Areas</h2>
<ul>
<li>Component Memoization</li>
<li>Code Splitting</li>
<li>Virtual Lists</li>
<li>State Management</li>
</ul>
<h2>Code Examples</h2>
<pre><code class="language-jsx">// Using React.memo for component memoization
const MemoizedComponent = React.memo(({ data }) =&gt; {
  return (
    &lt;div&gt;
      {data.map((item) =&gt; (
        &lt;Item key={item.id} {...item} /&gt;
      ))}
    &lt;/div&gt;
  );
});

// Using useMemo for expensive calculations
const memoizedValue = useMemo(() =&gt; {
  return computeExpensiveValue(a, b);
}, [a, b]);
</code></pre>
<h2>Best Practices</h2>
<ol>
<li>Use React.memo for pure components</li>
<li>Implement proper code splitting</li>
<li>Optimize re-renders</li>
<li>Use proper key props</li>
</ol>
